Outlook 2013 slow to start with Outlook 365 on Windows 7

Question

Hi,
I get to work, start up my PC. It's windows 7.
The first thing I do is kick off Outlook 2013 which piggy backs off office 365.
It takes a minute for the splash screen to appear, another minute of watch dots fly across the splash page then a minute while add-ins get applied.
Why does it take so long for the first two phases to complete?
What add ins do I actually need? I've disabled those I think surplus to requirements, but in reality if Outlook 2013/0ffice 365 need them why do they need to be added in at all?
Thanks.

Hi,
According to your description, outlook 2013 connects to Exchange online server very slowly.
If yes, we can try the following methods to narrow down the cause of the slow performance:
1. Try start your Outlook in  safe mode, and check the launch speed;
2. Check if you have enabled  Cache Exchange Mode, if no, enable it and try start Outlook, and check the launch speed;
3. Create a new profile with no email account, try start Outlook, and check the launch speed;
4. Create a new Profile with the other email account, try start Outlook, and check the launch speed;
Since the issue is related to Exchange online, I recommend you ask for help on our Exchange online forum:

Thanks for your understanding in advance.
If you have any question, please feel free to let me know.
